洒水车作为专用车中售后相对较少的车型,售后时经常出现的是一些小问题,比如环卫绿化洒水车在用过一段时间后抽不上来水,传动轴也在转,但就是水抽不上来。这个故障需要从以下几个方面来进行检查与排除:
As a relatively special customer service sprinkler car models, often appear when the customer service is some small problems, such as sanitation green sprinkler in use after a period of time not pumping water, the drive shaft in turn, but is not pumping water up. This failure needs to be checked and excluded from the following aspects:
一、管道阀门打错位置
First, the pipeline valve position
抽水时,先将抽水管连接在法兰盘上,然后将四位三通球阀的凹点位置扳**罐体管道方向(凹点所在方向管道为关闭状态,即连通抽水口与泵体之间的管道),然后打开直通球阀(手柄平行于管道时为打开,与管道呈90度角时为关闭),这才是正确的抽水阀门位置,打错其中任意一个管道都不能形成通路,自然是抽不上来水的。这也是新手操作洒水车常常会遇到的问题。
When pumping, first pumping pipe is connected to the flange, and then the four position three way valve concave position plate to the tank pipe direction (concave point direction of pipeline is closed, which is connected between the port and the suction pipe of the pump body), and then open the handle through valve (parallel to the pipe to open a 90 degree angle, and pipeline off), this is the pumping valve position of the right, the wrong one pipe can not form a natural pathway, is not on the water. This is a novice operating sprinkler often encountered problems.
二、滤网堵塞
Two, filter clogging
大多时候环卫绿化洒水车抽不上来水,销售人员都会建议客户先清洗一下过滤网。滤网三通位于四位三通阀门与洒水泵的中间,其二个端口连接在管道上,一进一出,另一个端口带一个可卸式平面,由四颗螺丝连接。将螺丝卸下,拿下面板,即可将中间的滤网取出。将滤网清洗完毕按原样装回即可。
Most of the time the sanitation green sprinkler pumping on the water, the sales staff will advise our client to clean the filter net. Filter three is located in the middle of three four through the valve and sprinkle water pump, and the other port is connected to the pipe, one into one, the other port with a removable plane, four screws connected. Remove the screws, remove the panel, you can remove the middle of the filter. Clean the filter screen and press it back.
因为洒水车不管是从外面抽的水,还是从罐体内放出的水,都必须经过此滤网进行过滤。因此,洒水车的三通滤网的滤芯是需要定期进行清洗的,特别是经常在野外进行取水的车辆,更应加大清理频率。
Because the sprinkler, whether it is pumping from the outside of the water, or the release of water from the tank, it must be filtered through this filter. Therefore, the three pass filter of the filter is the need for regular cleaning of the filter, especially in the field of vehicles often carried water, but should increase the frequency of cleaning.
三、管路密封不严
Three, the pipeline seal is not strict
有些用户在使用环卫绿化洒水车进行喷洒时,有时忘记打开喷水头开头,上车操作后发现不出水还继续加油门,造成管道内高压水流无法喷出,只能从相对比较薄弱的管道连接处(橡胶垫片)释放,导致胶垫在高压下被挤出,从而形成管路密封不严。
Some users were sprayed in the use of green sanitation sprinkler, sometimes forget to open the car after the operation at the beginning of the spray head, found no water to gas pipeline caused by high-pressure water inside the door, not only ejected from junction with pipeline relatively weak (rubber gasket) release, leading to the rubber pad is extruded under high pressure, thus the formation of pipe seal.
这种情况下管道连接处一般都会出现渗水现象。用户可将管道胶垫取出后重新组装一遍,对变形严重的胶垫应予以更换。在拧管道接头螺丝时,应遵循对角互拧的原则,不要逐个顺序进行操作,不要一次性将螺丝拧死,这样才能将橡胶垫片正确地安装上去。
In this case, there will be water seepage in the pipeline connection. The user can remove the pipe rubber pad and re assemble it again, and the rubber gasket with serious deformation should be replaced. When the pipe joint screw, should follow the principle of diagonal twist, not one by one in order to operate, do not screw the screw die, so that the correct installation of rubber gasket.
另一方面就是检查抽水管的密封度,看看抽水管是否有破损或者裂纹、或者阴阳端连接处没有卡到位等等,这些都会造成水泵无法将水顺序抽上来。
On the other hand is to check the sealing of the pumping pipe to see if there is damage to the pumping pipe or crack, or the junction of the junction of the Yin and Yang is not stuck in place, etc., which will cause the water pump can not be pumped up.
四、洒水车滤水器入水太深或者太浅
Four, sprinkler water filter into the water is too deep or too shallow
再就是查看洒水车滤水器是否入水太深,吸水高度大于允许高度,我们应当确认滤水器吸水高度小于5米,并且足够深置。吸水管的吸水头必须完全放置于水下,以免空气及入水管,导致真空度不良,水压过低而无法将水吸上来。
Then see the sprinkler water filter is too deep into the water, water absorption height is greater than the allowable height, we should confirm that the water filter is less than 5 meters high water absorption, and enough depth. The suction head of the water suction pipe must be completely placed in the water, so as to avoid the air and the water inlet pipe, the vacuum degree is bad, the water pressure is too low to suck up the water.
五、引水不足
Five, water shortage
洒水车配备的是离心式洒水泵,该泵每次吸水前,必须向水泵内加入一定量的引水,加完后必须关闭加水口。自吸式水泵**次使用时,需要加引水,以后则不必再加引水。在冬季时为避免泵体冻裂,应将洒水车罐体内和泵内的余水排空,再次作业时则需要为泵内加注引水。对于安装在洒水车上的洒水泵,加入引水时可将抽水管一端连接在法兰盘上,在另一端口进行注水动作,注水完成将该端口提升,让水流入泵内,即完成引水加注工作。
Sprinkler is equipped with a centrifugal pump, the pump every time before water, must be added to a certain amount of water to the pump, plus the need to close the water inlet. Self suction pump is used for the first time, need to add water, then don't need to add water. In the winter when the pump body to avoid cracking, should be more than the water tank and emptying the sprinkler pump, again when working for filling water pump. The sprinkler pump installed in the truck, adding water can be pumping pipe with one end connected to the flange on the water movement in a port, the port will complete the water, let the water into the pump, water filling is completed.
六、洒水泵真空不良
Six, sprinkler vacuum
洒水车水泵泵壳出现裂纹、或者叶轮、倒叶损坏、或者水封破损,都会影响真空度,出现水抽不上来,或者水压过小的现象。用户可根据洒水泵使用说明书上的故障排除方法进行维修或更换零配件。
Sprinkler pump shell cracks, or impeller, leaf damage, or seal damage, will affect the degree of vacuum, water pumping, water pressure is too small or the phenomenon. The user can repair or replace the spare parts according to the trouble shooting method of the sprinkling pump.
